China Engine - China leads the independent research and HVAC equipment HS code mappingdevelopment of engine technology. After decades of leapfrog development, China's engine manufacturing industry has gradually entered the stage of independent research and development from imitation and inheritance. As the core equipment of shipbuilding, aviation, ground transportation and other fields, engines play an extremely important role. Therefore, the Chinese government attaches great importance to the development of engine technology, and has increased investment in independent engine research and development in recent years, and is committed to becoming the world's leading engine manufacturing country. This article will discuss the history, current situation and future prospects of Chinese engines. The history of engines can be traced back to the history of engine manufacturing in China, which can be traced back to the early 20th century, when the first batch of engines in China appeared as a transplant and replication of foreign technology.In the mid-1930s, China officially entered the stage of independent engine design. The earliest aviation engine in China was developed and produced on the basis of Nanjing National Defense University of Science and Technology (i.e. the Central Aviation School). Since then, a number of engine manufacturing enterprises have emerged in China, such as 23 People's Liberation Army Engineering Forces, Harbin Motor Manufacturing Factory, Guilin Engine Manufacturing Factory, etc. These enterprises attach great importance to the research and development of engine technology, laying a solid foundation for the future of China's engine manufacturing industry. The current situation of engines. Today, China's engine manufacturing industry has made great progress. Against the background of the global economic downturn, China's engine market has maintained steady growth. China's engine consumption in aviation, shipbuilding, high-speed railway and other fields is increasing, which provides more opportunities and challenges for China's engine manufacturing enterprises.In 2017, the total output value of China's engine manufacturing industry reached 486.3 billion yuan, an increase of 11.5% year-on-year. Among them, the development and production of aviation engines has become one of the key points of China's engine manufacturing industry. China Airlines Aircraft Co., Ltd. (COMAC), the largest private civil aircraft manufacturer in China, has successfully developed the engine of the C919 large passenger aircraft, demonstrating the strength and potential of China's engine manufacturing industry. China's independent research and development and introduction and digestion in parallel. In addition to independent research and development, China's engine manufacturing industry has also made several attempts to introduce and digest engines in parallel. In the process of introducing technology, the application of welding technology is also a great progress in engine manufacturing. From the introduction to the gradual mastery of this technology in China, the level of welding technology has also gradually improved. Early engine students in GermanyProduction is achieved by welding technology, and China has gradually become one of the leaders of welding technology with the development of technology. Looking forward to the future, China's engine manufacturing industry needs to continue to carry forward the spirit of technological innovation, pay attention to market demand, strengthen international cooperation and other aspects to further improve the quality and competitiveness of products. The Chinese government should also increase its support in terms of policies and funds to promote China's engine manufacturing industry to a higher level. At the same time, China's engine manufacturing enterprises also need to make efforts to increase transformation and upgrading, improve independent innovation ability, establish an intellectual property protection system, etc., and improve the overall level of China's engine manufacturing industry in an all-round way. In the future, it can be predicted that China's engine manufacturing industry will definitely make more remarkable achievements and become one of the important manufacturers of global engine technology.Summarizing the achievements of China's engine manufacturing industry is encouraging. From the initial imitation to independent research and development, to the parallel learning of digestion and introduction, China's engine manufacturing industry has gone through a path of continuous pursuit, exploration and innovation, creating one "Made in China" achievement after another and showing it to the world. The courage and strength of China's manufacturing industry. Looking to the future, the development of China's engine manufacturing industry is full of opportunities and challenges. We believe that with the joint efforts of the government and enterprises, China's engine manufacturing industry will definitely usher in a bright future.
